mm: swap: clean up swap readahead
When I see recent change of swap readahead, I am very unhappy about
current code structure which diverges two swap readahead algorithm in
do_swap_page. This patch is to clean it up.
Main motivation is that fault handler doesn't need to be aware of
readahead algorithms but just should call swapin_readahead.
As first step, this patch cleans up a little bit but not perfect (I just
separate for review easier) so next patch will make the goal complete.
[minchan@kernel.org: do not check readahead flag with THP anon]
